.My invention relates to improvements in pipe ttings or connections, andmore particularly to a connection for the end of a horizontal pipesupport, usually :provided for the support for playground .swings andthe like.

An object of my invention is to provide an improved end pipe tting orsupport connection for supporting the .end of a horizontal pipe to whichplayground swings or the like may be suspended, andsaid connection alsoproviding positive means for securement to `angularly arranged vertical,lateral and endwise supporting and bracing pipes.

Another object of my invention is to provide an improvedend bearing andsupporting connection fora horizontal support, incorporating splitcooperating sections having means for clamping the same to cooperatingsupporting and bracing pipes, and the further addition of inwardlyextending positioning and locking studs carried by the connection forbeing received in opening formed in the several supporting and bracingpipes.

A still further object of my invention is to provide an improvedcomposite or sectional split end pipe tting or connection for supportinga horizontal supporting pipe and its bracing and supporting pipes, whichwill be highly efficient in operation, and quite inexpensive tomanufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of my application,

Figure 2 is a sectional view taken on the line 2 2 of Figure 1;

Figure 3 is a sectional view taken on the line 3 3 of Figure 1;

Figure 4 is a sectional view taken on the line 4 4 of Figure 2;

Figure 6 is a sectional view taken on the line 6 6 of Figure 5, and

Figure 7 is a sectional View taken on the line 1 1 of Figure 5.

Like characters of reference are used throughout the followingspecication and the accompanying drawings which form a part of myapplication.

In carrying out my invention, it will be understood that my inventioncomprises an end connection or pipe tting which will be secured at eachend of a horizontal pipe for supporting playground swings or othersuspended playground apparatus, and will provide means for attaching theconnections to vertical supporting bars or pipes, and also to angularlydisposed laterally and endwise extending bracing bars or pipes.

The connection will comprise a formation made from seven cooperatingsemi-cylindrical elongated pipe sections, each section being providedwith oppositely disposed laterally extending perforated locking lugs orears, which cooperate with similarly formed locking ears or lugs on thecooperating pipe sections, and which are adapted to receive lockingbolts for holding the several sections in assembled position. Also,several of the sections are provided with inwardly directed, integrallyformed locking studs, which are adapted to be received either withinlocking openings on the other sections, or in the cooperating supportingand bracing bars or pipes, the

whole assembly providing for the positive support ,i

of a horizontal supporting bar or pipe, vertically disposed supportingbraces, oppositely disposed laterally extending bracing pipes, andoutwardly and downwardly extending bracing pipes at the opposite ends ofthe horizontal supporting bar or p1pe.

By referring to the drawings, I designate the main or horizontalsupporting bar or pipe by the numeral I, the vertical supporting bracesby the reference numerals 2 and 3, respectively, the lateral downwardlyand outwardly extending braces by the numerals 4 and 5, and the endoutwardly and downwardly extending braces by the numerals 6 and 1.

The base clamping members 8 and 9 are 3 adapted to lie adjacent eachother and to support the end of the bar or pipe I, each of said membersbeing provided with laterally and downwardly extending clamping sectionsI il and I I for the reception of the bracing pipes 4 and 5. Thesections I0 and I I are further tied together by means of the integrallyformed cooperating bracing ties I2 and I3, arranged adjacent the lowerends of the said sections I0 and II. Cooperating clamping sections I4and I5 having reduced upper ends are provided for securing to thevertical supporting pipes or braces 2 and 3, said reduced ends beingadapted to lit around the cross bracing ties I2 and I3, and to besecured thereto by means of the bolt I6, which extends through said endsand ties.

A cap member I1 is provided for cooperation with the base clampingmembers 8 and 9, and is adapted to fit over the upper surface of the endof the bar or pipe I, while spaced perforated ears or lugs 'I8 and I9cooperate with the lugs 20 and 2| formed on the sections 8 and 9, and tobe secured togther by means of the bolts 22 and 23.

The clamping sections I and II are further provided with cooperatingperforated locking ears or lugs 24 and 25, and are adapted to receivethe locking bolts 26 and 21 for securing them in fixed position.

The end brace supporting members comprise cooperating sections 28 and29, which are bent and reduced at their upper ends to fit into or seatwithin the adjacent end of the base and cap members, the shoulders 30and 3| on the sections 28 and 29 engaging and seating on the said endsCooperating per-Y of the base and cap members. forated ears or lugs 32and 33 are formed on the sections 28 and 29, and are held in assembledposition by means of the bolts 34 and 35, which are positioned throughYthe said ears or lugs.

A pair of inwardly directed integrally formed.

locking studs 36 and 31 are formed on the cap member and are adapted tobe received within corresponding openings 38 and 39, formed in end brace28 and the bar or pipe I, respectively. Locking studs 40 and 4I areprovided respectively in the section 29 and the sections I0 and I I forpositioning in openings or sockets formed in the end bracing pipes 6 and1, and in the laterally extending bracing pipes 4 and 5. Similar lug 42is formed .in the clamping section I5 for cooperation with an opening orsocket formed in the vertical supporting pipes 2 and 3.

From the foregoing description, it will be ap` parent that a pluralityof cooperating split clamps are provided held together by means of thelugs or ears and bolts, and further secured to the several bars andbraces by means of the locking studs and cooperating sockets. Theconnection provided affords the full equivalent of a single castinghaving a plurality of locking means, but in fact, made from sevenseparate cooperating sections, which interlock in such a mannertoproduce a highly eicient fitting.

Many minor changes in detail of construction may be resorted to withoutdeparture from the spirit of the invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Pat- Vent of the United States is:

1. A pipe connection comprising a plurality of interlocking partsconsisting of a pair of base clamping members having integrally formedangularly disposed depending brace clamping sections interconnectedadjacent their outer extremities, cooperating clamping sections havingreduced ends clamped about the interconnecting portions of said braceclamping sections and having a locking bolt extending through saidreopenings, bolts extending through said openings for holding saidconnection in assembled relation, and inwardly extending locking andposis tioning studs formed integrally on the inner surfaces of saidmembers and sections for locking reception in openings formed in thepipes connected to said connection.
